CARPET-FASTEN ER.

SPECIFICATION forming part of Letters PatentNo. 723,586, dated March 24, 1903.

Application filed J'annary 3,1903- Serial No. 137,636. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL D. OOSTEN- BADER, a citizen of the United States, and a resident of Lehighton, in the county of Carbon and State of Pennsylvania, have invented new and useful Improvements in Oarpet-Fas' teners, of which the following is afull, clear, and exact description.

The invention relates to certain novel and useful improvements in a device for securing carpets, and has particular application as a fastener for retaining a stair-carpet in proper position and to prevent sagging or derangement of the same.

It is my object to provide an improved staircarpet fastener which shall have but onescrew or nail therein, which is to be embedded or driven into the stairs, and at the same time shall securely clamp the carpet and prevent any movement of the same.

A further object of my invention is to so.

construct and arrange the various portions of the device that there shall be no liability of the same being easily damaged or broken, the result being that I provide an extremely durable article which shall last for a long period and is so simple that it may be placed in position for use by even unskilled persons.

In addition to the above advantages I have as an object the providing ofa fastener which may be manufactured and sold at but comparatively little expense.

WVith these and other objects of a like nature in view my invention consists in the construction, combination, and arrangement of parts, as is herein described in this specification, delineated in the accompanying drawings, and set forth in the appended claims.

Reference is to be had to the accompanying drawings,forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a view of a section of a stairway, showing my improved device applied thereto. Fig. 2 is an enlarged plan view of the fastener, the inoperative non-active position of the same-being shown in dotted lines. Fig. 3 is a top edge view of the device in its operative positiomthe stair-steps being shown in section; and Fig. is a sectional view taken. on the line 4 4 of Fig. 2. I

Referring now to the accompanying drawthreaded shank 8 of the screw 9.

'as is clearly shown in Figs. 2 and 3, and comprises a cup-shaped disk portion 1, provided circumferentially with a number of short studs or pins 2, adapted to be driven into the Wood of the stair and assist in retaining the disk thereon. This cup-shaped portion or disk is provided with a semicircular slot or groove 3, adapted to permit the passage of the end portion 4 of the arm 5 of the device. This arm is pivoted to the stair through the medium of a screw 6, which passes centrally through the cup-shaped disk 1 and is threaded into the stair portion. If desired, the small pins 2 may be omitted from the base portion, the screw 6 forming the only retaining means for the device. It will therefore be seen that the appearance of the stairs is not marred or ruined by numerous holes being formed therein.

The arm or flat plate 5 is relatively long as compared with the other portions of the device and may be ornamented in any suitable manner. This arm is apertured at its nonpivoted end 7, and this aperture is preferably threaded to receive the correspondingly- Between the head portion of the screw 9 and a washer 10,clamped thereon,is secu red the ornamental head portion 11 of the device, which serves as a finger-grip or handhold in adjusting the device to the carpet. be of any desired shape or form, being shown in the present instance as star-shaped. To the inner end of the shank portion of the screw 8 is secured a concavo-convex plate 12, held against movement on the shank of the screw through the medium of a washer 13. A spring-pin 14: passes through the screw next to the washer 13, and 'a second springpin 15 also passes through the extreme end portion of the shank on the concave side of the disk, the latter being therefore held between the pins and prevented from moving 'on the screw. A spring-pin 16 passes through the screw'next to the washer 10.

From the above description, taken in connection with the accompanying drawings, the

This head portion may Mg been applied to operation of my improved device will be readily apparent. The cup-shaped disk 1, in which is pivoted the arm 5, is fastened to the body of the stairway, and the carpet B havthe stairs the arm is shifted from the approximately vertical position (shown in dotted lines in Fig. 2) to a horizontal postion and presses against the surface of the carpet. The dish-shaped portion 12 may then be tightened or clamped to bear upon the carpet with increased pressure by turning the star-shaped finger-grip toward the right, which causes the arm to be moved outward from the body of the stair, and as the arm presses against the upper semicircular edge forming the slot in the disk pressure will be exerted by the dish-shaped plateagainst the carpet, thus retaining the latter securely in position.

It will thus be seen that the device may be adjusted to fit any degree or thickness of carpet and may be easily and readily applied to or removed from a stair.

' While I have shown and herein described one particular embodiment of my invention, it is of course to be understood that I do not limit myself to the precise details of construction shown herein, as there may be modifications and variations in some respectswithout departing from the principle of the invention or sacrificingany of the advantages thereof.

It is to be further observed that the device may be constructed of any suitable material, and, if desired, the relatively long fiat arm may be formed of a spring metal,so that when in its operative position it may more readily exert clamping pressure upon the carpet.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A carpet-fastener comprising an arm, a

disk having a slot therein, a screw passing through the disk and arm, securing said disk rigid but permitting the arm to move in the path of said slot, and means carried at the opposite end of the arm for clamping the carpet to a stairs, substantially as set forth.

2. A carpet-fastener comprising an arm, a disk having a slot therein, a screw passing through said arm, securing the disk rigid with the stairs but pivotally supporting the arm, a screw-rod passing through a threaded aperture in the free end of the arm, a finger-grip attached to the head of the screw-rod, and a clamping-plate secured to the outer end thereof, substantially as set forth.

3. In a fastener for securing carpets to stairways, the combination of a pivoted member, means for limiting the movement of the same upon its pivot, an adjustable screw-rod carried by the pivoted member, and a carpet-engaging member, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
